One of the key accused in the drug haul case from Zirakpur allegedly attempted suicide, even as Punjab Police maintained that no decision has been taken yet on summoning boxer Vijender Singh after the Olympic medallist's name cropped up.

"The key accused Anup Singh Kahlon
attempted suicide. He took out a wire from the bucket used for bathing and tried to slit his wrist with it, but he is out of danger," Fatehgarh Sahib's senior superintendent of police (SSP), HS Mann said on Saturday.

The accused was safe and provided medical aid, the SSP said, adding that no major injury was sustained in the suicide attempt.

Kahlon, an NRI, would now be booked for attempt to suicide.

When asked if Vijender Singh, who hails from Haryana's Bhiwani district, would be questioned, the SSP said, "we haven't taken any final decision on summoning him."

He said investigation in the case was under progress as the six accused arrested so far were being interrogated. Based on their revelations further course of action would be decided, the SSP said.

"We are investigating the case. As of now, no decision on Vijender Singh has been taken. All aspects of the case are being investigated. We have not decided on calling him yet," he said.

However, police are probing the role of Vijender's fellow pugilist Ram Singh, he said, adding that Ram had been asked to help the investigators again on Saturday.

Asked about reports that Ram, a native of Patiala, purportedly confessed that he had taken heroin at least six times from the arrested peddlers and consumed it with Vijender, the SSP said, "we are verifying these. I cannot comment further at this stage."

Vijender, 27, a Haryana Police DSP rank officer, has trashed allegations that he has links with the alleged NRI drug dealer arrested by the Punjab Police, saying the "ridiculous charges" would be proved wrong in investigations.

Police had recovered 26-kg of heroin, estimated around Rs. 130 crore, from Kahlon's house in Shivalik Vihar in Zirakpur near Chandigarh on Thursday.

The car of Vijender's wife Archana was found by police outside the NRI's house.
